In this paper, various shapes of planar monopole antenna on different ground plane structures are presented. It is designed for the 1-2 GHz frequency band for L-band application. A monopole of square, circular, triangular and hexagon shape is mounted vertically on the dielectric of glass epoxy (FR4 lossy substrate) with relative permittivity of 4.3, thickness of 1.6 mm above the ground plane th...

A novel design of a CPW fed printed monopole antenna for dual polarization applications is proposed in this paper. The monopole is formed of a rectangular patch embedded with a hour-glass shaped slot. In a modified version of the antenna, an additional spiral shaped slot is incorporated in the ground plane. The overall dimensions of the antenna are kept at 40× 40mm. The impedance bandwidth achi...

In this paper a monopole antenna for WLAN and WiMAX frequencies is proposed. The given antenna is composed of a rectangular patch monopole antenna having an E-shaped slot with two backward slits on the substrate and a defected ground plane. The antenna exhibits single band, which creates an impedance bandwidth of 2 GHz for the working band of 4-6 GHz. The various characteristic parameters like ...

A compact printed ultra wideband (UWB) monopole antenna with multi-notched characteristics is presented. By inserting multiple E-shaped slot in micro strip feed line and ground plane, additional resonances are excited. The multi notch has been created by embedding a pair of – L shaped arm in the radiating patch and a modified E-slot defected ground structure in the feeding line. The designed an...

This paper describes an antenna system combining Global Navigation Satellite System (GNSS) with Iridium satellite communications and UHF 225-512 MHz communications on a handset to provide an integrated Communications Navigation (Comm/Nav) antenna. The GPS/GNSS/Iridium antenna is a folded Quadrifilar Helix Antenna (QHA) with novel features which improve frequency coverage compared to existing QH...

The ultra wide band antennas are required in applications where larger bandwidth for the transmitting signal is needed. They cover wide bandwidth in the range from 500 MHz to the frequencies above 8000 MHz. In this paper, a review of various techniques to realize ultra wide band microstrip antennas (MSA) is presented. They are realized by using different techniques like basic planar monopole an...

Body Centric Wireless Communication (BCWC) has been topic of much research in recent years. In this manuscript, a novel low-cost microstrip patch antenna is designed for on-/off-body communication with a dual-band operation. The proposed structure exhibits a monopole-like radiation pattern at 2.45 GHz and a broadside radiation at 4.8 GHz, simultaneously. Lateral dimensions of 42 mm × 46 mm and ...

In this paper, a microstrip-fed hexagonal shape ultra-wideband (UWB) monopole antenna with triple notched bands is presented. The antenna consists of a microstrip feed line, a regular hexagonal shape radiation patch with a complementary split ring resonator (CSRR) and a pair of inverted T-shaped conductor-backed planes embedded in the antenna backside. Notched bands can be easily controlled by ...

For the purpose of wideband operations, a printed monopole antenna fed by a microstrip line is investigated. A single element is studied before using it to form a linear array or two-dimensional antenna array system. The antenna element has a single T-shaped radiator fed by a microstrip line. This design is found to be useful for the entire C-band frequency range centered at 6 GHz. The computed...
